Got them working with YARG at the weekend, still having a few issues with vjoy and my yamaha dte3 not working with clone hero.
Was pretty simple in the end. Set the switch on the drum controller to midi, plugged an otraki midi to usb cable into midi-out and the pc and configured the drumkil as per the quick setup tutorial.
Grand daughters been playing a few tracks at 50% speed and playing along which isnt bad considering she's only been learning at school for 6 months.
